Relationship of the UK with the European Union has been fluctuating quite in recent times although a significant role is played by the UK in European Union creation. There has been development of sentiments regarding the EU membership of UK in the last few decades in a constant manner which caused the 1st referendum in the year 1975. More than 67 percent of the constituents of the United Kingdom took the decision to stand beside the membership of UK in the EU EEC (European Economic Community). It was the party of labor in the 1980s by which the withdrawal of the UK was advocated from the EU.
